Application mea september 3, 1925. serial No. 54,209.

rl'his invention relates to machines for extractingclinker or other material from furnaces, ovens, retorts, etc., and comprises all .improvements over the prior art which are disclosed in this application. One object is to sto support the frame of the machine that the shovel side of the machine may be brought up close to the furnace opening, while at the same time the supporting wheels on the shovel side of the machine are placed sufficiently far back from the furnace opening so that the supporting rail for these wheels can be so placed as not to substantially interfere with the clinker falling into the hopper mouth. Also by thus having the shovel side of the main frame relatively near the mouth opening, a shorter ram bar can be used to reach the back of the furnace. This not only makes for less spring and whipping action in the ram bar in operation, but also permits of the ram bar beingshort enough to clear the posts at the rear of the ram bar, thus enabling the operator to more elfectivcly keep his mind on his work of extracting clinker, and hence enable him to extract clinker at a faster rate.

rl`he above and other objects which will hereinafter appear, are attained by new and useful improvements as disclosed in this ap To ena-ble others skilled in the art to fully understand the essential features of the improvements, drawings have been annexed as a part of this disclosure.

Fig. 1 is a vertical section of a Zinc oxide furnace and the adjacent yard construction with the clinker extractor shown in end view.

Fig. 2 is a plan View of the clinker extractor.

Fig. 3 is a side elevation of the clinker extractor.

1 represents a Zinc oxide furnace having loose grate bars 2 extending from the front to the rear of the furnace. Opening 3 has a bottom 4 upon which is secured a filler plat-e 5 by means of countersunk screws 6, the filler plate being of substantially the same thickness as the grate bars 2. The outer edge of the ller plate 5 is preferably beveled at 7 to aid shovel 16 in properly entering opening 3.

Outside of the furnace is a yard construction comprising a floor 3, posts 9 and hopper mouth 10. Mounted on floor 3 are rails 11, 12 securedin place by any suitable means.

Rail 12 projects over the hopper mouth 10 only to a slight extent and therefore does not substantially interfere with the clinker falling into'the hopper mouth from opening 3. But if rail 12 is thus placed, and if the clinker extractor 13 is provided with a normal frame and wheel construction, the extractor frame 14 must be so far from the furnace opening 3, that for practical construction and-operation, ram bar 15 must be of exceptional length to reach the extreme back of the furnace. This extra length of ram bar 15 would result in more spring'and whippingaction of the ram bar while the shovel 16 is working near the back of the furnace, and when the shovel 16 were retracted to position shown in Fig. 1, the longer ram bar would strike posts 9. y

The extractor 13 comprises a frame 14 mounted upon Wheels 17, 18, 19,20. Viheels 17, 18 are keyed to axles 21, 22 which are journalled in opposite sides of frame 14 and carry collars 23, 24 which cooperate with wheels 17, 18 to retain the axles from substantial longitudinal movement. lvlheel 19 is smaller than wheel 17 and is located beneath frame 14 and keyed on axles 25 carried by two part bearings 26, 27 belted to frame 14. TWheel 2O is the same size as wheel 19 and is located partly beneath frame 14 and keyed on axle 28 carried by two-part bearings'29, 30 bolted to frame 14.

Formed on the top of the frame 14 is a ring track 31 on which travels the supporting rollers 32 of ram carriage 33 which is "l swiveled on vertical shaft 34. Electric motor 35 is fastened to frame 14 and acts through gearing 36, 37, 38, 39, universal joint 40, screw 41 and nut 42 pivoted to ram carriage 33, to swing the rain carriage in either direction about shaft 34 as a pivot, by causing the motor 35 to rotate in either direction by known electric cont-rol devices.

Keyed on shaft 34 is a pinion 43 meshing with rack 44 on rain bar 15 carrying shovel 16. Also `keyed on shaft 34 below the top of the frame 14 is a large bevel gear 45 meshing with bevel pinion 46 which freely turns on shaft 47 and has clutch teeth 48. Splined on shaft 47 is a clutch. 49 having clutch teeth on its opposite sides and being adapted to be slid in opposite directions on shaft 47 by means of clutch lever 50 swinging a bar 51 whiehpasses through clutch 49 and lits loosely in a socket il "i 52 in frame li. Pinion 53 is 'free on shaft l? and has clutch teeth 5l. Electric motor 55 rotates shaft 4.7 through gears 5G, 57. By moving the clutch l5) toward pinion 53, the clutch slides under and raises the litting bar 58 projecting from brake dog 5), thus lifting brake dog 5U ont or' locking engagement With pinion 53. ily moving clutch l-E) further until its Gluten teeth engage clutch teeth 5a, pinion is rotated, and hence gear 60 keyed on shaft Gl is rotated and through bevel pinions ('32, 553, on opposite ends ot shaft 6l, bevel gears (ill, (155, are rotated and rotate axles 2l, 22, and consequently Wheels l?, itl, to more the machine along the tracl. Motion in either direction obtained by reversing motor 5.5 in a Well known manner. By shitting clutch #i9 in. the opposite direction, lifting bar 5S is released to permit brale dog 59 to fall into engagement with the teeth of" pinion to held the machine in position Where itis placed, By shifting the clutch still further, it engages clutch teeth el@ on bevel pinion 46 and through berel gear -l-, shaft 3l and pinion a3 ant. rack Llei, op crates ram bar 15 laterally ot the machine. Reciprocating movement ot' ram bar 15 is obtained by reversing motor The rain bar is held and guided by rollers in a manner broadly similar to that disclosed in Patent 768,067 to McConnell.

Thus by the mechanism described, the machine can be shifted along" a track to any position desired. The ram carriage can also be sirivcled about shaft Slt to any angle desired, and the shovel can be reeiprocated into and out oi a iurnace opening.

lllheels 1T, 18 operate to shift the machine along the track and to support one side of the machine. Wheels 19, 20 support the opposite or shovel side ot' the machine, but are not driving Wheels.

All changes which properly come `within the spirit and range of equivalency of the following claims are intended to be embraced Within the scope of the claims.

I claim:

l. In a machine vfor extracting clinkcr and the like, a trame, a shovel mounted at one side oi" the irame and adapted to be reeiprocalted transversely of said traine, a pair oit' axles extending transverselyroi: and mounted in the opposite sides ot', said trame, a. Wheel mounted on each axle at the side of' the `frame remote from the shovel, a second pair ot axles mounted on the trame, a u'heel mounted on each ot said second pair of axles having` a portion Within the line passing longitudinally oie the irame along the outside of the shovel side traine mountings of said first pair ot' axlesl Q. The machine set forth in claim l, in which the Wheels on said second pair oi axles are mounted beneath the shovel side of said trame,

3. rThe machine set forth in claim l, in which the axles o1 said second pair ot axles are farther apartJ from each other, than the distance between the axles ot' said lirst pair of axles.
